Fixed OS/2 windows being shown when setting position/size. Moved the OS/2 specific DW_OS2_NEW_WINDOW flag into os2/dw.c. Deprecated and essentially removed DW_FCF_SHELLPOSITION and DW_FCF_NOBYTEALIGN. These were OS/2 specific and are set automatically now... FCF_SHELLPOSITION was causing the positioning problems that necessitated the window being shown to set the size and position. Right now SHELLPOSITION isn't used at all... causing shell positioning to not work. I hope to have a way to allow shell positioning to work again soon but the idea I had to do this did not work.
